So, I know that I've been told by several sources to not use calcium powder that has D3 in it. But, the closest pet store to me seems to only sell it with D3. So, my question is, why is it such a big deal to have it/not have it? Does it do any actual harm to the animal, or just found unnecessary? Links to articles or just a brief explanation would be very helpful. Thanks.
